http://androidforums.com – I dropped my phone from about 2 feet to carpet, had case, and didnt think much of drop until this am, when i noticed a very thin line right in the middle of screen, i see glass replacement ads in ebay and amazon now for a do it yourself solution, has anyone gone this route?.....have seen some videos on youtube, etc, still not 100 % convinced i want to do it myself....also, if anyone has taken phone to be professionally fixed, how much will it run?.....thanks!
